MAX1220, MAX1257, MAX1258 12-Bit, Multichannel ADCs/DACs With FIFO, Temperature Sensing, And GPIO Ports

The MAX1220 MAX1257 MAX1258 integrate a 12-bit, multichannel, Analog-to-digital converter (ADC), and a 12-bit, octal, digital-to-analog converter (DAC) in a single IC. These devices also include a Temperature Sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI"-/QSPI"-/MICROWIRE"-compatible serial Interface The ADC is available in 8 and 16 input-channel versions. The octal DAC outputs settle within 2.0s and the ADC has a 225ksps conversion rate.
All devices include an internal reference (2.5V or 4.096V) for both the ADC and DAC Programmable reference modes allow the use of an internal reference, an external reference, or a combination of both. Features such as an internal 1C accurate Temperature Sensor FIFO scan modes, programmable internal or external Clock modes, data averaging, and AutoShutdown" allow users to minimize power consumption and processor requirements. The low glitch energy (4nV s) and low digital feedthrough (0.5nV s) of the integrated octal DACs make these devices ideal for digital control of fast-response closed-loop systems.
The devices are guaranteed to operate with a supply voltage from +2.7V to +3.6V MAX1257 and from +4.75V to +5.25V MAX1220 MAX1258 . These devices consume 2.5mA at 225ksps throughput, only 22A at 1ksp throughput, and under 0.2A in the shutdown mode. The MAX1257 MAX1258 feature 12 GPIOs, while the MAX1220 offers four GPIOs that CAN be configured as inputs or outputs.
The MAX1220 is available in a 36-pin thin QFN package. The MAX1257 MAX1258 are available in 48-pin thin QFN package. All devices are specified over the -40C to +85C temperature range.
